The livestock sector is responsible for a significant amount of wastewater globally. The microalgal-bacterial consortium (MBC) treatment has gained increasing attention as it is able to eliminate pollutants to yield value-added microalgal products. This review offers a critical discussion of the source of pollutants from livestock wastewater and the environmental impact of these pollutants. It also discusses the interactions between microalgae and bacteria in treatment systems and natural habitats in detail. The effects on MBC on the removal of various pollutants (conventional and emerging) are highlighted, focusing specifically on analysis of the removal mechanisms. Notably, the various influencing factors are classified into internal, external, and operating factors, and the mutual feedback relationships between them and the target (removal efficiency and biomass) have been thoroughly analysed. Finally, a wastewater recycling treatment model based on MBC is proposed for the construction of a green livestock farm, and the application value of various microalgal products has been analysed. The overall aim was to indicate that the use of MBC can provide cost-effective and eco-friendly approaches for the treatment of livestock wastewater, thereby advancing the path toward a promising microalgal-bacterial-based technology.

The increasing global demand for sustainable protein sources necessitates the exploration of alternative solutions beyond traditional livestock and crop-based proteins. Microalgae present a promising alternative due to their high protein content, rapid biomass accumulation, and minimal land and water requirements. Furthermore, their ability to thrive on non-arable land and in wastewater systems enhances their sustainability and resource efficiency.

Estrogens have attracted extensive attention because of their harmful effects on organisms such as endocrine disturbance and reproductive toxicity. This study investigated the spatial and temporal distribution and ecological risk assessment of 7 targeted estrogens in surface water in a seasonal freeze-thaw basin. It mainly includes three natural estrogens, estrone (E1), 17β-estradiol (E2) and estriol (E3), two synthetic estrogens, 17α-ethinylestradiol (EE2) and diethylstilbestrol (DES), and two phenolic environmental estrogens, bisphenol-A (BPA) and nonylphenol (NP).

The development of highly operational, reusable, multifunctional antibacterial agents has become an urgent need of the hour in terms of environmental safety and sustenance. This study was aimed at determining newly emerging bacterial pathogens in the wastewater effluent of broiler chicken and dairy cattle farms, beside their slaughterhouses. Also, the study assesses the biocidal effect of chitosan (CS), terminator disinfectant (TD), copper oxide nanoparticles (CuO-NPs), and terminator-based copper oxide nanoparticles (TD/CuO-NPs) against isolated emerging bacterial pathogens from wastewater effluents.

Livestock farms are important reservoirs of antibiotic resistance genes (ARGs). However, how wastewater irrigation from swine farms affects the surrounding environments, especially water bodies, is not fully understood. In this study, the occurrence pattern and potential risk of ARGs and mobile gene elements (MGEs) in a biogas slurry from a large-scale swine farm and its surrounding environments were investigated.
